摘要 为了研究超高速碰撞产生等离子体的粒子能量对航天器电路中元器件的毁伤,获得超高速碰撞产生等离子体粒子能量的时空分布特性是十分必要的。基于超高速碰撞产生稀薄等离子体中带电粒子的运动速度、等离子体的扩散特点,推导出等离子体的粒子能量密度与带电粒子密度及带电粒子运动速度的关系式。进而通过对超高速碰撞2024-T4铝靶实验采集的原始数据分析,利用Matlab编程得到了超高速碰撞2024-T4铝靶产生膨胀等离子体云物理过程中,等离子体的粒子能量密度与带电粒子持续时间及被测点到碰撞点距离的时空分布规律。 In order to study damage of plasma energy generated by hypervelocity impact on spacecraft electronic compo nents, it is necessary to obtain temporal and spatial distribution characteristics of particle energy induced by hypervelocity impact. The relationship between the particle energy density and the particle velocity was derived based on charge particle motive velocity and diffusive characteristic. We obtained temporal and the spatial distribution rules of particle energy in thin plasma cloud genera- ted by hypervelocity impact 2024-T4 aluminum targets based on analysis of original data from impacting 2024-T4 aluminum target experiment and Matlab computer codes.
